Mine doens't i.e. my anemometer stopped sending data after 8 months of use and have to fork out another $160 to get it from US to Poland becuase their local resellers are asking nearly $300 for the same item! Presume it's much cheaper in the US but turns out to be very expensive to run anywhere outside which is a shame. I am a little dissapointed about VP2 quality & life expectancy. At least Davis should replace items that fail often at a reasonable price.
